Minibwa is a hybrid of bwa-mem and minimap2 and the successor of bwa-mem for short-read mapping. ~4X/2.5X as fast as bwa-mem/bwa-mem2 for WGS reads at comparable accuracy. Native support of directional bisulfite-seq. Applicable to long reads. Preprint at arxiv.org/abs/2606.15357

The team's first preprint is out! Led by ‪ ‪@vishnuprasoodanan.bsky.social‬‬ & @omaistrenko.bsky.social , we asked a question (almost) as old as microbiology: how many prokaryotic species exist on Earth? More specifically, how much diversity is "hiding" in existing metagenomic data? A 🧵.

Do people in the same household share strains when they have the same species? How many cells transmit when a strain is shared? Can strain composition be dynamic when species composition is stable? We answer these and related questions for the facial skin microbiome in our latest paper. 🧵[1/10]
